Study Notes

Combining Forms and Terminology

  • Ren/o indicates kidney surgeries and diseases; nephr/o is the more commonly used combining form.
  • Pyel/o refers to the renal pelvis; py/o does not mean renal pelvis.
  • Urethra's combining form is urethr/o, while ureter/o is incorrect for urethra.

Kidney Structure and Functions

  • Each kidney weighs approximately half a pound; both are located on each side of the spinal column.
  • Kidneys serve as the primary organs for excreting toxic waste.
  • Each kidney is composed of over a million nephrons responsible for filtration.
  • The outer region of the kidney is the cortex, whereas the medulla refers to the inner region.

Urinary System Operations

  • Ureters, not urethras, transport urine from the kidneys to the bladder.
  • The glomerulus in each nephron is essential for blood filtration.
  • Urinary bladder acts as a temporary reservoir for urine before expulsion through the urethra.

Medical Conditions and Diseases

  • Cystitis is the inflammation of the urinary bladder.
  • The presence of blood and proteins in a urinalysis indicates possible glomerular disease.
  • Hydronephrosis represents an abnormal condition characterized by fluid accumulation in the kidneys.
  • Uremia describes the buildup of toxic waste substances in the bloodstream.

Procedures and Surgical Terms

  • Nephrectomy refers to the surgical excision of a kidney.
  • Urethropexy denotes the surgical fixation of the urethra.
  • Pyelolith signifies the existence of stones within the renal pelvis.

Suffixes and Prefixes

  • The suffix -ia implicates an abnormal condition.
  • The suffix -cele relates to herniation or hernia.
  • Suffix -lithiasis refers to the presence of stones.

Key Concepts

  • Micturition is the process of voiding urine via the urethra.
  • Dysuria denotes painful or difficult urination.
  • Cystourethrogram is not a sound wave imaging procedure; it involves contrasting imaging techniques.
  • Nephrolithiasis is the term for the presence of kidney stones.
  • Azot/o is the combining form for nitrogen, crucial for understanding conditions related to nitrogenous wastes.
